To all whom zt may concern:

Be it known that I, RICHARD E. BIERD, a citizen of the United States,residing at Carrollton, in the county of Saginaw and State of Michigan,have invented certain new and useful Improvements in Punching-Bagsupports; and I do declare the following to be a full, clear, and exactdescription of the invention, such will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to punching-bag supports.

The object of the invention is to provide a support of this character`in which provision is made for the free swiveling or turning of thebag-supporting member under the movements of the bag, thereby allowingthe latter to swing with more *freedom and with greater sensitivenessunder the influences of the blows from the bag-puncher and at the sametime obviating the twisting strain in the hanger ordinarily produced.

With this and other objects in View, which will appear the nature of theinvention is better understood, the invention consists of a punohing-bagsupport embodying certain improved features of Construction andcombination and arrangement of parts, as will be hereinafter more fullydescribed, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a central vertical section ofa punching-bag support embodying my invention. Fig. 2 is a detail topplan view of the same, showing the opening for the introduction of theantifriction bearings into the raceway.

Referring now more particularly to the drawings, the numeral 1represents an annular supporting-bracket adapted to be secured by screwsor other suitable fastenings to a suitable supporting-frame and taperedupon its under side to the opening therein to form a bearing-surface 3of sufficient strength and area for the formation of an annular groove4. Supported from this bracket is a bag suspending bell or hanger 5,which is threaded at its upper end for engagement with a flangedbearing-ring 6, having in its outer *face a groove 4', facing the saidgroove 4 in the bracket, the said two grooves providing an annularraceway for a series of antifriction roller-balls 7,Which adapt thebearing-ring and bag-suspending bell to swivel or order to provide 'forthe introduction of the balls into the raceway, the bracket andbearing-ring are formed with notches adapted to be brought intocoincidence to form an opening of restricted area for the insertion ofthe balls, the size of the opening being such with respect to thediameter of the balls employed that the latter must be forcedtherethrough by a blow from a punch or suitable instrument, thuspreventing the balls after they have been once inserted from becomingdisplaced or forcing their way out of the raceway.

The bag suspending bell or hanger .5 is provided with anoutwardly-fiaring abutmentllange 9 and a restricted throat or passage10, leading from the under side thereof into a chamber or recess 11. Thechamber or rccess is adapted to receive the upper end of the bagsuspending rod or rope, which is formed into a knot or provided with astop disposed within said recess and ofgreater diameter than the1,assage 10 to secure the rope or red against witldrawal. If desired,the llange may act as an abutment to limit the play of the bag, or itmay be employed solely as a stop to limit the swing of the rope underthe movement of the bag.

By the Construction above described it will be seen that the bell orhanger is swiveled to turn or rotate u mn the bracket 1, and thus isadapted to yield under the movements of the bag, thereby allowing thelatter to swing with more freedom and with greater sensitiveness underthe influences of the blows from the puncher and at the same timeobviating the twisting strain on the hanger ordinarily produce( Furtheradvantages of this Construction Will be 'readily apparent to thoseversed in the art.

From the foregoing description, taken in connection with theaccompanying drawings, the Construction and operation of the inventionwill be 'eadily understood without requiring a more extendedexplanation.

arious changes in the form, proportion, and the minor details ofconstruetion may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus l'ully described my invention, what I claim as new, anddesire to secure by rotate upon the supporting-bracket 1. In
